Image display apparatus

Abstract

An image display apparatus including a display panel, a holding member holding four sides of the display panel, and cushioning members disposed between the display panel and the holding member such that a pressing force depending on an amount of deformation is applied to the display panel, wherein a pressing force acting on the display panel through the cushioning member for a lower side among the four sides of the display panel is higher than a pressing force acting on the display panel through the cushioning members for other sides of the display panel.

What is claimed is: 
     
       1. An image display apparatus comprising:
 a display panel; 
 a holding member holding four sides of the display panel; and 
 cushioning members disposed between the display panel and the holding member such that a pressing force depending on an amount of deformation is applied to the display panel, wherein 
 a pressing force acting on the display panel through the cushioning member for a lower side among the four sides of the display panel is higher than a pressing force acting on the display panel through at least one of the cushioning members for the other sides of the display panel. 
 
     
     
       2. The image display apparatus according to  claim 1 , wherein, when the image display apparatus is operative, a compression ratio of the cushioning member for the lower side is higher than a compression ratio of the at least one of the cushioning members for the other sides. 
     
     
       3. The image display apparatus according to  claim 1 , wherein a thickness of the uncompressed cushioning member for the lower side is larger than a thickness of the at least one of uncompressed cushioning members for the other sides. 
     
     
       4. The image display apparatus according to  claim 3 , wherein the cushioning member for the lower side and the at least one of the cushioning members for the other sides are elastic members having the same property. 
     
     
       5. The image display apparatus according to  claim 1 , wherein, when amounts of deformation of the cushioning members for the lower side and the at least one of the cushioning members of the other sides are equal to each other, the pressing force acting on the display panel through the cushioning member for the lower side is higher than the pressing force acting on the display panel through the at least one of the cushioning members for the other sides. 
     
     
       6. The image display apparatus according to  claim 5 , wherein the cushioning member for the lower side has a property different from a property of the at least one of the cushioning members for the other sides, and the cushioning member for the lower side has a larger elastic modulus than the at least one of the cushioning members for the other sides. 
     
     
       7. The image display apparatus according to  claim 1 , wherein a shape and a physical property of the cushioning member are determined such that, when a usage environment condition changes and as a result the display panel is warped, the pressing force acting on the display panel through the cushioning member becomes weaker than a pressing force that causes display unevenness in the display panel. 
     
     
       8. The image display apparatus according to  claim 1 , wherein the holding member is a frame that holds the display panel from front, and
 the cushioning members are front surface elastic bodies disposed between the display panel and the frame. 
 
     
     
       9. The image display apparatus according to  claim 1 , wherein the holding member is a panel holder that holds the display panel from a rear surface thereof, and
 the cushioning members are rear surface elastic bodies disposed between the display panel and the panel holder. 
 
     
     
       10. The image display apparatus according to  claim 1 , wherein the display panel is rotatable, the image display apparatus is used in one of a first state or a second state in which the image display apparatus has been rotated through 90 degrees from the first state, and the pressing force acting on the display panel through the lower side in the first state and through the lower side in the second state is higher than the pressing force acting on the display panel through the at least one of the cushioning members for the other sides. 
     
     
       11. The image display apparatus according to  claim 1 , wherein a pressing force acting on the display panel through the cushioning member for at least one of four sides of the display panel which corresponds to a lower side when the image display apparatus is operative is higher than a pressing force acting on the display panel through the at least one of the cushioning members for other sides of the display panel. 
     
     
       12. The image display apparatus according to  claim 1 , wherein the pressing force acting on the display panel through the cushioning member for the lower side of the display panel is higher than a pressing force acting on the display panel through each of the cushioning members for two of the other sides of the display panel,
 each of said two of the other side of the display panel is connected to the lower side of the display panel. 
 
     
     
       13. The image display apparatus according to  claim 1 , wherein the pressing force acting on the display panel through the cushioning member for the lower side is higher than a pressing force acting on the display panel through each of the cushioning members for all of the other sides of the display panel. 
     
     
       14. The image display apparatus according to  claim 1 , wherein the holding member holding four front sides of the display panel is a first holding member, and
 the cushioning members disposed between the display panel and the first holding member are first cushioning members, and 
 the image display apparatus further comprises; 
 a second holding member holding four rear sides of the display panel, and 
 second cushioning members disposed between the display panel and the second holding member, wherein 
 a second cushioning member disposed on the lower side of the display panel faces a first cushioning member disposed on the lower side of the display panel. 
 
     
     
       15. The image display apparatus according to  claim 1 , wherein the four sides of the display panel are four peripheral sides of the display panel. 
     
     
       16. The image display apparatus according to  claim 1 , wherein the cushioning member for the lower side and at least one of the cushioning members for the other sides are formed of a same material.
